正丁醇催化转化为高附加值产品是生物质精细化工的重要途径。本工作报道了非金属多壁碳纳米管（CNT）作为双功能催化剂在氧辅助正丁醇转化反应中的应用。碳纳米管上正丁醇的氧化脱氢和脱水分别通过氧化还原和酸催化途径生成醛和烯烃化合物。CNT在温和的反应条件下表现出高活性（超过50%的正丁醇转化率）和稳定性（超过120小时）（
Catalytic conversion of n-butanol to high-value-added product is considered as a highly important route towards biomass derived fine chemicals. The present work reports the applications of non-metallic multi-walled carbon nanotube (CNT) as bifunctional catalysts for oxygen assisted n-butanol conversion reactions. Oxidative dehydrogenation (ODH) and dehydration of n-butanol on CNT yielded aldehyde and alkene compounds via redox and acid catalytic routes, respectively. CNT exhibited high activity (over 50% n-butanol conversion) and stability (over 120 h) under gentle reaction conditions (
